The tuner includes an analog tuner and a digital tunerto receive both an analog broadcasting signal and a digital broadcastingsignal.

The communicator 103 communicates with at least one supply source torequest related image content of the primary image content, and receivesthe related image content from the supply source according to control ofthe controller 115. The communicator 103 according to the presentexemplary embodiment may communicate with the supply source connectedthrough a wired/wireless LAN, modem, etc.

The supply source supplies the primary image content, and may includebroadcasting stations (e.g. terrestrial broadcasting stations such asSBS, KBS and MBC, regional broadcasting stations and cable broadcastingstations), and a server storing the primary image content.

As shown in FIG. 2, the communicator 103 according to the presentexemplary embodiment communicates with respective broadcasting stations150, 160 and 170, each of which comprises a server which stores theprimary image content therein, and receives the related image contentstored in the server of the broadcasting stations 150, 160 and 170. Thereceiver 101 receives the primary image content supplied by therespective broadcasting stations 150, 160 and 170 in real-time through aradio frequency (RF) signal. The receiver 101 and the communicator 103may be provided as an integrated chip (IC).

The signal processor 105 processes the primary image content supplied bythe communicator 103, and converts the primary image content into aformat displayable as an image on the display unit 107, e.g. into adigital RGB signal, and outputs the signal to the display unit 107 underthe control of the controller 115.

The signal processor 105 may provide various functions corresponding tothe format of the inputted image signal. For example, the signalprocessor 105 may provide functions such as an analog to digital (A/D)conversion function to convert various types of inputted analog imagesignals into digital signal in a particular format; a digital decodingfunction; a scaling function to scale a vertical frequency, resolution,or a picture ratio of an inputted digital image signal and/or analogimage signal according to an output protocol of the display unit 107,and a predetermined formation conversion function.

The display unit 107 displays the primary image content processed by thesignal processor 105. The display unit 107 may comprise digital lightprocessing (DLP) technology, a liquid crystal display (LCD) and a plasmadisplay panel (PDP). Alternatively, the display unit 107 may be providedas an external unit.

The UI generator 109 generates a user interface (UI) of a listillustrating at least one related image content supplied from the supplysource under the control of the controller 115. The UI generator 109 mayinclude an on screen display (OSD) generator or may be included in thesignal processor 105 processing the primary image content. The generatedUI is outputted and displayed on a part of the display unit 107.

The user input unit 111 includes a key to select a command to play therelated image content of the primary image content currently displayed.The user input unit 111 may include a remote controller or a menu keyprovided on a casing, and a key signal generator to generate a keysignal corresponding to key manipulation. The related image content mayinclude titles, content, genres, etc. of the primary image content,which will be described in more detail later.

Particularly, the user input unit 111 according to the present exemplaryembodiment may include a hot key to select a command to play the relatedimage content while the received primary image content are displayed.The user input unit 111 may further include a number key and a directionkey to select a channel, a function key to select a function provided inthe image processing apparatus 100, etc.

The storage unit 113 stores the primary image content processed by thesignal processor 105 if the key to play he related image content isselected through the user input unit 111 and the related image contentsupplied from the supply source are played. The storage unit 113 maycomprise at least one of a hard disk, a random access memory (RAM), aflash memory, etc.

If the key used to input the command to play the related image contentis selected through the user input unit 111 while the received primaryimage content is being processed, the controller 115 controls the signalprocessor 105 to process the related image content supplied from thesupply source. The controller 115 may comprise a CPU, a microcomputer,etc.

More particularly, if the primary image content is received through thereceiver 101, the controller 115 controls the signal processor 105 toprocess the received primary image content and display it on the displayunit 107. If a channel is selected through the user input unit 111, thecontroller 115 tunes to the selected channel to receive the primaryimage content, and processes and displays the received image content.

The controller 115 determines whether the key to play the related imagecontent is selected through the user input unit 111 while the primaryimage content is processed by the signal processor 105.

The related image content may include image content such as titles,contents, genres, etc. of the currently-processed image content.Preferably but not necessarily, the related image content may includeimage content broadcast before the currently-viewed image content. Forexample, if the currently-viewed drama is the fifth episode, the relatedimage content may comprise the fourth, third, second and first episodes.

If the key to play the related image content is selected through theuser input unit 111, the controller 115 checks additional informationincluded in the primary image content. The additional information mayinclude a broadcasting station transmitting the image content, thetitle, contents, playing time, file size of the image content, etc.

The controller 115 requests the broadcasting station transmitting theprimary image content, i.e. the supply source through the communicator103 to supply the related image content, based on the checked additionalinformation. If the supply source transmits the related image content inresponse to the request, the controller 115 controls the signalprocessor 105 to process the transmitted related image content to beplayed.

The controller 115 generates a query to request the list of the relatedimage content to the supply source transmitting the image content, byusing the additional information. If the supply source transmits thelist of the related image content in response to the query, thecontroller 115 controls the UI generator 109 to generate a UI of thelist.

For example, the related image content may include the previouslybroadcast image content. In this case, if a user is currently viewingthe 17th episode of a drama, a UI A may be generated as shown in FIG. 3.The user may select one of the related image content on the listdisplayed in the UI A through the direction key provided in the userinput unit 111.

If one of the related image content in the UI A is selected through theuser input unit 111, the controller 115 controls the communicator 103 torequest the supply source to transmit the selected related imagecontent. If the supply source supplies the selected related imagecontent, the controller 115 controls the signal processor 105 to playthe supplied related image content.

If the signal processor 105 processes the related image content, thecontroller 115 controls the storage unit 113 to store the primary imagecontent received by the receiver 101 and processed by the signalprocessor 105.

Moreover, the controller 115 controls the signal processor 105 toprocess and display the primary image content stored in the storage unit113 or controls the UI generator 109 to generate a UI of a listillustrating the stored primary image content if the processing of therelated image content is finished.

Thus, a user may select and view the related image content of thecurrently-viewed primary image content through simple key manipulation.If the related image content of the displayed primary image content isselected, the currently-viewed image content is additionally stored sothat a user may view the stored primary image content after viewing therelated image content.

A control method of the image processing apparatus 100 according to theexemplary embodiment of the present invention is hereinafter describedwith reference to FIG. 4.

As shown therein, if the primary image content is received (operationS1), the controller 115 controls the signal processor 105 to process anddisplay the received primary image content (operation S3).

The controller 115 determines whether a user selects the key to play therelated image content of the displayed primary image content (operationS5).

If it is determined at operation S5 that the key to play the relatedimage content is selected, the controller 115 requests the supply sourcesupplying the primary image content to transmit the related imagecontent (operation S7).

If the supply source supplies the related image content, the controller115 controls the signal processor 105 to process and play the relatedimage content (operation S9).

The control method of the image processing apparatus 100 according tothe exemplary embodiment of the present invention will be described inmore detail with reference to FIG. 5.

As shown in FIG. 5, if the primary image content are received (operationS11), the controller 115 controls the signal processor 105 to processand display the received primary image content (operation S13).

The controller 115 determines whether a user selects the key to play therelated image content of the primary image content (operation S15). Ifthe key to play the related image content is selected, the controller115 requests the supply source to transmit a list of the related imagecontent (operation S17).

The controller 115 checks the additional information included in theprimary image content, generates and transmits a query requesting thelist of the related image content to the supply source supplying theprimary image content, by using the additional information of the imagecontent.

The controller 115 controls the UI generator 109 to generate the UI ofthe list illustrating the related image content supplied from the supplysource (operation S19).

If the related image content selected from the UI through the user inputunit 111 is to be played (operation S21), the controller 115 requeststhe supply source to supply the selected related image content(operation S23).

If the supply source supplies the related image content, the controller115 controls the signal processor 105 to process and play the suppliedrelated image content (operation S25).

If the related image content is played, the controller 115 controls thestorage unit 113 to store the primary image content received by thereceiver 101 and processed by the signal processor 105 therein(operation S27).

As described above, the controller 115 may control the signal processor105 to resume playing the stored primary image content or control the UIgenerator to generate the UI of the list illustrating the stored primaryimage content if the playing of the related image content is finished.

Thus, a user may select and view the previously-broadcasted relatedimage content of the currently-viewed primary image content throughsimple key manipulations. As the image processing apparatus 100 requeststhe related image content, a user does not need to search the relatedimage content one at a time.

Additionally, if the related image content of the displayed primaryimage content is selected, the currently-displayed primary image contentis additionally stored. Thus, a user may consecutively view the primaryimage content after viewing the related image content.

As described above, the exemplary embodiment of the present inventionprovides an image processing apparatus which may be easily manipulatedto select and view related image content of currently-viewed primaryimage content, and a control method thereof.

Additionally, the exemplary embodiment of the present invention providesan image processing apparatus and a control method thereof whichautomatically requests, receives and displays related image contentselected by a user, and improves user's convenience as a user does notneed to search the related image content one at a time.

Further, the exemplary embodiment of the present invention provides animage processing apparatus which additionally stores acurrently-displayed primary image content if related image content ofthe displayed primary image content are selected so that a user mayconsecutively view the primary image content after viewing the relatedimage content, and a control method thereof.
